System and devices for digital media distribution

ABSTRACT

A device includes a memory for storing digital media, a transfer module, and a processor. The media includes first data that associates the media with the device, second data authorizing the device to play back the media, and third data authorizing the device to transfer a copy of the media. A transfer includes transfer data identifying the copy uniquely relative to the device. The processor implements instructions to receive a request to transfer a copy of the media to a peer device, create a copy of the media that includes the first data and the transfer data, and direct the transfer module to transfer the copy to the peer device and send a transaction record including the first data and the transfer data to a server.

RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.11/558,443 entitled “Methods and Devices for Digital MediaDistribution,” filed on Nov. 10, 2006, the disclosure of which is herebyexpressly incorporated by reference.

FIELD OF THE DISCLOSURE

Embodiments are related to digital media. More particularly, embodimentsare related to the distribution of digital media.

BACKGROUND

Digital media has become a primary form of distribution of music, video,news articles, games, and the like. Currently, digital media purchasedand used by individuals is usually protected from illegal copying by arestriction on which device can playback the digital media. The playbackof the digital media occurs where a license for the digital media ispresent for the particular device intended for playback and/or for theparticular user of the device used for playback. Accordingly, adifferent user with a different device cannot playback digital mediawith such restrictions. Such restrictions prevent sharing of the digitalmedia from an initial purchaser to an entity who may also be interestedin having a functional copy of the digital media.

The popularity of a particular digital media work is often increased byword of mouth. Initial purchasers may allow another individual tolisten, watch, or otherwise experience the playback of a particulardigital work on the purchaser's device and the other individual maydecide to purchase a copy of the digital media for their device as well.For example, an initial purchaser may allow a friend to listen to apurchased song, and the friend may then wish to obtain a copy of thesong as well. However, to prevent illegal copying, restrictions such asthose discussed above prevent the song from being copied for use by thefriend, so the friend must go through the normal channels ofdistribution to obtain a licensed copy of the song that the friend mayplayback.

Requiring the friend to go through the normal channels of distributionmay result in the friend not following through with the purchase of thedigital media. For example, the friend may choose not to do so due tothe effort required or may simply forget to do so at some later time.Furthermore, the initial purchaser is given no motivation to encouragethe friend to follow through with obtaining a licensed copy of thedigital media. Accordingly, the number of transfers, and particularlypurchases, for a given digital media work suffer.

DETAILED DESCRIPTION OF THE DRAWINGS

Embodiments provide for a brokerage model to be established for thedistribution of digital media by utilizing initial recipients of thedigital media as the distribution force. Accordingly, word of mouthbetween peers regarding a particular digital media work becomes atransfer and a potential sales transaction, rather than relying on theinterested entity to subsequently make a transfer and possibly apurchase through normal channels of distribution that are unrelated tothe interaction with the initial recipient. Transfers may thereby occurat the moment the initial purchaser is demonstrating the digital mediato the interested entity, and the initial purchaser may be compensatedfor the transfer so that the initial recipient is motivated todemonstrate the digital media and to encourage other entities to obtaina licensed copy. The licensed copy may be obtained via a direct transferfrom the device of the initial recipient to that of the interestedentity as a descendant of the licensed copy of the initial recipient orby the device of the interested entity accessing a network link that isprovided by and associated with the initial recipient.

FIG. 1 shows an example of the operating environment for the variousembodiments. In FIG. 1, a first device 102 of an initial recipientincludes content 104 representing one or more digital media files. Theinitial recipient has previously received the content 104 such as byaccessing a digital media distribution server 112 to download the mediacontent and, if required, purchase it. The digital media distributionserver 112 maintains a digital media database 116 which contains one ormore digital media files that are accessible for download by devicesconnected to network 110 such as the Internet. The server 112 alsomaintains a transactional database 114 that maintains a record of thetransfers made, and for transfers that are purchases it maintains theform of payment provided for the purchase. The transactional database114 may interface with various payment mechanisms including conventionalclearing houses that process credit card transactions where the digitalmedia is purchased.

FIG. 1 additionally shows a second device 106 of a next purchaser.Presumably, the user of the first device 102 is a peer of the user ofthe second device 106, and the user of the first device 102 demonstratesthe digital media content 104 to the user of the second device 106. Indemonstrating the digital media content 104, it is further presumed thatthe user of the second device 106 becomes interested in the digitalmedia content 104 and wants to obtain a copy for use on the seconddevice 106. At this point, one of various alternative mechanisms forproviding a copy 108 of the digital media content 104 to the seconddevice 106 and for providing payment to the user of the first device 102for the distribution effort is implemented. Each of the variousmechanisms is discussed below.

FIG. 2 shows an example of the components of the first and seconddevices 102, 106 of FIG. 1. Devices 102, 106 may include smart phones,personal digital assistants (PDA) with communications capabilities,dedicated music players with communications capabilities, and the like.

The devices 102, 106 have the functionality to playback digital mediafiles and also to send and receive the files and access networkaddresses in order to complete transfers and purchase transactions.According to one embodiment, the devices 102, 106 have the ability tocommunicate on a peer-to-peer basis where the digital media file itselfmay be transferred and/or where a hyperlink for accessing the digitalmedia file may be transferred. Additionally, the devices 102, 106 havethe ability to communicate over a networked connection to exchange datawith remote network resources such as the server 112 in order tocomplete purchases for and download the digital media files.

As shown in FIG. 2, the devices 102, 106 include a processor 202 thatcommunicates with various components in order to provide the digitalmedia playback and perform the brokerage functions. The processor 202implements instructions to perform the necessary logic for performingthe playback and brokerage functions, and the instructions may behard-wired digital logic or firmware. In this example, the processor 202interacts with the various modules through a data bus 214, but it willbe appreciated that one or more of the modules may be incorporated intothe processor 202.

A memory module 204 is present in order to store the digital media files206. The memory module 204 may be of various forms including variousforms of read only memory, random access memory, and/or a combination ofthe two.

The processor 202 and memory 204 are examples of computer readable mediawhich store instructions that when performed implement various logicaloperations. Such computer readable media may include various forms ofstorage media including electronic, magnetic, and optical storage.Computer readable media may also include various forms of communicationsmedia, such as wired and wireless connections used to transfer theinstructions or send and receive other data messages.

An input module 208 allows for users to enter input, including commandsfor starting playback of digital media as well as for initiating thetransfer of digital media files or links thereto to other devices. Theinput module 208 may include a touch screen, a keypad, buttons,directional pads, and the like.

An output module 210 provides the audio and/or video output that isperceived by the user upon playback of the digital media as well as thegraphical user interface, web browser, and other applications providedby the processor 202 for basic operation. The output module 210 mayinclude a display screen such as a liquid crystal display (LCD), one ormore speakers, a headphone output, and the like.

A transfer module 212 provides the transfer of data into and out of thedevice 102, 106. The transfer module 212 of this example may downloaddigital media files via a direct connection to another device or througha network connection to remote resources. Furthermore, the transfermodule 212 of this example may upload records of the transaction, eitherthe record for the seller or the record for the buyer, such as thepayment method to be used for purchases of digital media. The transfermodule 212 may include a wired network interface such as Ethernet, awireless network interface such as Wi-Fi (or other 802.xx standards)and/or cellular, and may include a peer-to-peer interface such as awired IEEE 1394 or USB connection or a wireless Bluetooth or infraredconnection.

FIGS. 3A and 3B show an example of the operational flow that may occurin the environment of FIG. 1 with the devices 102, 106 utilizing thecomponents of FIG. 2. FIG. 3A begins at a point where device 102 hasalready obtained, by purchase or otherwise, a copy of digital media fromthe server 112 or from another device of another broker. This digitalmedia includes media data, discussed in more detail below with referenceto FIG. 4, that identifies the digital media and specifies to theprocessor 202 of device 102 that the digital media is available for acopy to be transferred to another device 104. The media data may specifyadditional details as well, such as but not limited to: a fixed salesprice or limits on the sales price, a grace period during which thetransferred copy of the digital media may be played back without yethaving been purchased, a limit on the usable lifetime of the digitalmedia for the first device 102, a limit on the lifetime that a copy ofthe digital media is transferable, and a limit on the usable lifetimefor copies of the digital media that are transferred.

It is further presumed in FIG. 3A that the user of the first device 102has demonstrated the digital media to the user of the second device 106.An additional presumption is that the user of the first device 102 andthe user of the second device 106 have reached an agreement regarding acopy of the digital media being provided from the first device 102 tothe second device 106 so that the user of the second device 106 hasaccess to a licensed copy for playback. The agreement may involve asales price that has been agreed to where the digital media at issuedoesn't already specify a fixed sales price.

At this point, the user of the first device 102 inputs a request totransfer the digital media file to the second device 106 at requestoperation 302. The processor 202 of the first device 102 then accessesthe digital media file from memory 204 and prepares the digital mediafile for transmission to the second device 106 at file operation 304.Here, media data that was included in the original digital media fileobtained by the user of the first device 102 may be maintained astransaction information for the copy in certain embodiments. Suchretained transfer media data may include the identification of thedigital media and/or may include usage profile data that controls usageof the digital media at a given device, such as any playback controldata including digital rights management (DRM) data, limitations onplayback time, playback attempts, and so forth. In other embodiments,some of this transaction information specified by the transfer mediadata may change, such as the identification data that forms the basisfor licensing of the digital media and implementation of the DRM, wherethe copy being created for transfer may have a transfer media data thatuniquely identifies it relative to the copy of the initial recipient.Furthermore, in various embodiments, there may be transfer media datathat is appended to the digital media file or a portion of the existingdata may be modified when transferring the digital media file.

For example, where the transaction is a purchase, the transactioninformation specified by the transfer media data may include transactionparameters. The transaction parameters may include information such aspurchase information that is appended to the existing media data of thecopy of the digital media file being transferred. The purchaseinformation may include various elements, including an identification ofthe seller, billing data such as the sale price, and any other termsnegotiated between the user of the first device 102, i.e., the broker orseller, and the user of the second device 106, i.e. the recipient orbuyer. The first device 102 may allow for the user to enter terms of thesale to create the purchase information being appended. However, whereone or more terms of the sale have been fixed by when the initial copyof the digital media was fixed, these items, this media data may bemaintained. Examples of fixed terms may include the sale price, thelifetime of the license for playback of the digital media, the lifetimeof the license to be a re-seller or broker of the digital media, etc.

FIG. 4A shows an example of the digital media file contents once theprocessor 202 of the first device 102 has prepared the copy of thedigital media file for transfer to the second device 106. The copy 402of the digital media file includes a header portion 404 as well as thedigital content portion 406. The header portion 404 is analyzed whenplayback of the digital media file 402 is requested to allow for variousdeterminations. For example, the header 404 may be analyzed to determinethe proper playback mode such as audio versus audio/video, compatibilitywith digital media players being implemented by the processor, andwhether the current user has the license to playback the digital mediafile on the present device. The digital content portion 406 is where thedata content to be played back is located.

The header 402 of this example includes various fields and correspondingmedia data stored within those fields. Field 408 includes dataspecifying the file type, the version, and the like to enable theprocessor to properly play back the contents. This field allows theprocessor 202 to utilize the correct settings and/or play backapplication for play back of the contents.

Field 410 provides transfer media data that includes an identificationof the digital media file that serves to identify the digital media filefor licensing and/or tracking purposes. The identification may be aserial number or similar character string that allows the digital mediafile to be tracked and distinguished relative to other digital mediafiles that may have the same content but have different serial numbers.Furthermore, field 410 may include a serial number indicating that thepresent copy 402 is a descendant of a digital media file previouslypurchased, such as by using a “0.01” or similar scheme. Identifying thedigital media file as a descendant allows tracking of the transfer ofcopies of digital media files from brokers, where each descendant fileis indicative of a sale through a broker as opposed to a sale throughnormal channels of distribution. The digital media file may beidentified as a descendant of an original copy purchased through anormal channel, such as by using “0.01” or identified as a descendant ofa descendant, such as by using “0.01.01” and in this manner theidentifier distinguishes the digital media file from the original copywhile still indicating a relationship to the original copy.

The header 402 may include additional fields of information such asfield 412 where the sales price is located for instances where thedigital media is purchased. Again, the sales price may result fromnegotiations whereby the user of the first device 102 enters the agreedupon sales price, or the sales price may be fixed such that field 412 isdirectly copied from the originally purchased copy of the digital mediafile by the processor 202 or may be populated by the processor 202 basedon what the sales price for a descendant copy must be.

Field 414 may be present to specify a grace period for playback of thedigital media file by the second device 106 prior to payment for thedigital media file being provided by the user of the second device 106.The grace period may be fixed by the original content provider oralternatively may be negotiated between the broker and the buyer. Thegrace period may be specified in terms of a set expiration date relativeto the date when the copy 402 is transferred, may be a set number oftimes the digital media file may be played back, or some other manner oflimiting playback.

Field 416 specifies the playback controls or DRM for the copy 402. Thisfield 416 may be required to contain certain data, referred to asauthorization data, in order for playback to occur once the grace periodhas ended. This authorization data represents to the DRM logic that thecopy 402 is a valid licensed copy. The authorization data is absent orotherwise inaccessible within the second device 106 upon the initialtransfer but may be provided to the second device 106 for inclusion infield 416 upon payment being received by the user of the second device106. DRM logic is a manner of preventing unauthorized use, the detailsof which are disclosed in U.S. Pat. Nos. 7,120,250 and 7,103,574, bothof which are incorporated herein by reference in their entirety.

Field 418 may be included to provide data that specifies how thetransaction can be recorded and, in the case of a purchase, how paymentis made in order for the authorization data to be provided. This datamay specify a clearing house for receiving payment and the method forsubmitting it. Such data may specify a network address that may beaccessed by the second device 106 upon an option to complete thepurchase being provided to and selected by the user of the second device106.

Field 420 may be included to specify information about the broker, oruser of the first device 102, who is transferring the copy to the userof the second device 106. This field 420 may include an identificationof the broker, such as a name or broker number. It may further specifyadditional information such as when the broker completed the transfer tothe second device 106. This information may be used to supplement theidentification data from field 410 when the record of the transaction isbeing submitted to the back-end server 112. The identification of thebroker in the record of the transaction, discussed in more detail belowwith reference to FIG. 4B, allows the back-end server 112 to tracktransfers including sales by the broker and to compensate the brokeraccordingly.

Returning to FIG. 3A, once the processor 202 of the first device 102 hascompleted preparing the copy of the digital media file for transfer, thecopy is then presented to the transfer module and is transferred over adirect transport to the second device 106 at transfer operation 306. Asdiscussed above, the direct transport may be through one of varioustypes of transport mechanisms, including wired or wireless.

The processor 202 of the first device 102 then submits a record of thetransaction to the back-end server 112 or other network location atrecord operation 308. The field 418 may be referenced to determine thenetwork address where the record of the transaction is submitted. Therecord of the transaction allows the back-end server 112 to process thetransaction as necessary to receive payment, license the transferredcopy, and compensate the broker.

An example of the record of the transaction is shown in FIG. 4B. Therecord 450 is a data file that includes various fields of information,including at least a portion of the information included in the mediadata header 404 of the copy 402 that has been transferred to the seconddevice 106. The record submitted by the first device 102 in this exampleincludes field 452 which includes the identification of the digitalmedia that has been transferred. As discussed above in relation to field410, this identification information may identify the digital media thathas been transferred to be a descendent of a digital media filepurchased through normal channels and/or as a descendant of adescendant. Field 454 may be included to indicate the sale price, ifany, for the transfer as also specified in field 412, such as the saleprice that has been negotiated between broker and buyer or a fixed saleprice. Field 456 may be included to further identify the broker as alsospecified in field 420.

Field 458 provides information about the recipient of the transfer. Forexample, field 458 may identify the recipient such as by name and mayalso identify the method of payment specified by the recipient where apurchase is taking place. However, field 458 may be omitted from therecord submitted by the broker from the first device 102. As discussedbelow, the second device 106 may also submit a record of the transactionand the record submitted by the second device 106 may include all of thefields shown in FIG. 4B including the field 458. The back-end server 112may utilize the buyer date of field 458 to complete the transaction andto also enroll the recipient as another broker for the digital mediathat has been obtained.

Returning to FIG. 3A, after the first device 102 has attempted totransfer the copy of the digital media file, the second device 106 thenreceives the copy at reception operation 310 through the complementarytransfer module 212 of the second device 106. The processor 202 of thesecond device 106 then stores the digital media file in memory 204 ofthe second device 106 at record operation 312. Presumably, the user ofthe second device 106 will then attempt to access the digital media filefor playback such that, in accordance with this example, an option maybe presented to the user to complete the transaction such as a purchasefor the digital media file transfer or continue to utilize the digitalmedia during the grace period if not yet expired. Upon the user of thesecond device 106 selecting to complete the transaction, the processor202 of the second device then further acts on the digital media file byparsing the header 404 to obtain the data necessary to generate therecord of the transaction 450 and submit it to the proper networkaddress at record operation 312. The buyer information may include theauthorization to charge a credit account or to otherwise obtain paymentfor the transaction where a purchase is occurring.

As shown in FIG. 3B, the server 112 receives the record 450 submittedfrom the first device 102 and receives the record 450 submitted from thesecond device 106 at reception operation 314. Upon receiving the tworecords, the server 112 of this embodiment performs a comparison of thedata of the two to verify the transaction information and therebyauthorize the transaction when the two records match. This comparisonmay be performed to ensure that for a given digital media beingidentified, the sale price asserted by the broker and the sale priceasserted by the buyer do not differ and that the transfer actuallyoccurred rather than being fictitious. In receiving both records, theserver 112 can detect whether any discrepancies are present thatindicate either the broker or the recipient are attempting to manipulatethe sale price. The server 112 can maintain records of brokers,recipients, and the number of times a discrepancy has occurred in orderto determine whether to ban participants from the brokerage process.

Additionally, the server 112 obtains the buyer information thatspecifies the method of payment by the recipient where a purchase isoccurring, such as a particular credit account to cover the sale price.The server 112 may then determine whether the form of payment isadequate as part of verifying the transaction information.

Once the server 112 has verified that the records match and that theform of payment is valid, the server 112 then submits payment to anaccount of the broker, i.e., the user of the first device 102 at paymentoperation 316. For example, the broker may have a bank account, creditcard account, or other electronically accessible account where funds canbe deposited by the server 112. As an alternative, the server 112 maygive the broker credits toward the purchase of additional digital mediafiles, either for direct purchase through normal channels or forpurchase from other brokers.

The server 112 also transfers authorization data, e.g., a license codefor the serial number or other identifier of the digital media,necessary for the playback of the copy 402 of the digital media to thesecond device 102 at transfer operation 318. As discussed above, thisauthorization data is used by the processor 202 implementing the DRMlogic to determine that the copy 402 is a valid and licensed copy forthe user of the second device 106.

The authorization data sent from the server 112 is received by thesecond device 106 at reception operation 320. The processor 202 of thesecond device 106 then appends the authorization data to media datafield 416 of the header 404 for the copy 402 stored in memory 204 of thesecond device 106 at data operation 322. The processor 202 of the seconddevice 106 then checks the header 404 for the authorization data withinfield 416 when the user of the second device 106 requests playback ofthat particular digital media file at playback operation 324.

This discussion of FIGS. 3A and 3B provide for the direct transfer ofthe digital media file from the first device 102 to the second device106. As an alternative, the digital media file may instead be madeaccessible via a dedicated network link such as a hyperlink on the worldwide web. FIG. 5 shows one example of an operational flow for providinga brokerage where the transfer occurs via the network link.

The operational flow shown in FIG. 5 begins at a point where device 102has already received a licensed copy of digital media from the server112 or from another device of another broker. As with FIG. 3, thisdigital media may include media data that identifies the digital mediabut the media data may also specify a network location, e.g., ahyperlink, where a copy of the digital media file may be accessed. Themedia data may specify additional details as well, such as but notlimited to a fixed sales price or limits on the sales price.

It is further presumed in FIG. 5 that the user of the first device 102has demonstrated the digital media to the user of the second device 106.An additional presumption is that the user of the first device 102 andthe user of the second device 106 have reached an agreement regarding acopy of the digital media being accessed by the second device 106 fromthe network location as specified in the media data or otherwise knownby the broker so that the user of the second device 106 has access to alicensed copy for playback. The agreement may involve a sales price thathas been agreed to where the digital media at issue does not alreadyspecify a fixed sales price.

Prior to the broker having demonstrated the digital media to the user ofthe second device 102, the server 112 at network operation 502establishes the hyperlink for access to a copy of the digital media filethat has been purchased by the user of the first device 102, i.e., thebroker. The hyperlink may be associated with the broker so that when thehyperlink is accessed, the identity of the broker need not be presentedsince accessing the hyperlink already brings to light the broker to becompensated.

Upon the user of the first device 102 and the user of the second device106 reaching an agreement, the hyperlink is entered into the seconddevice 106 in order for the second device 106 to access the copy of thedigital media file at input operation 504. The link may be enteredmanually, such as by the user of the first device 102 telling the userof the second device 106 what the link is so that the user of the seconddevice 106 then manually enters the link. Alternatively, the link may bestored either as part of the media data of the digital media file on thefirst device 102 or is otherwise stored on the first device 102 and istransferred via the transfer module from the first device 102 to thesecond device 106.

As discussed above, where a purchase is occurring, the agreement mayinvolve a negotiation for a sale price or the sale price may be fixed.Where there is a negotiation, the sale price may be entered by the userof the first device 102 via an input field provided by the processor 202and the sale price may then be included in a record of the transactionas shown in FIG. 4B where the record is then submitted to the server 112via an address specified in the media data. The sale price may also betransferred to the second device 106 in the same manner as transferringthe link, or the user of the second device 106 may enter it manually ina field provided by the processor 202 of the second device 106.

The user of the second device 106 may then instruct it to access thehyperlink, or the hyperlink may be automatically accessed as a result ofthe transfer of the hyperlink to the second device 106. Upon accessingthe link, the server 112 may communicate with the second device 106 inorder to receive payment and buyer details to purchase the digitalmedia. According to one or more embodiments, the initial visit to thehyperlink may instead involve selecting an option to download thedigital media file for use during a grace period prior to completing thetransaction for the digital media file transfer. In that case, thedigital media file like file 402 of FIG. 4A that is downloaded includesa grace period specified in field 414 but may lack the authorizationdata necessary for field 416. Upon accessing the hyperlink, the seconddevice 106 may also submit a record of the transaction like that shownin FIG. 4B to the server 112 to specify the sale price asserted by thebuyer.

Upon the second device 106 accessing the hyperlink to complete thepurchase, the server 112 then completes the purchase based on the recordof the transaction including the payment method of the buyer at purchaseoperation 508. If the buyer is purchasing the digital media on the firstvisit to the hyperlink, as opposed to only downloading the digital mediafor playback during a grace period, then the digital media file isprovided with the authorization data present in field 416. If the buyeris purchasing the digital media on a subsequent visit after havingalready downloaded the digital media file for purposes of playbackduring a grace period, then either a replacement version of the digitalmedia file that includes authorization data is provided for download orthe authorization data is provided for download so that it can beappended to field 416 for the copy already in memory 204 of the seconddevice 106. Upon the user of the second device 106 completing thepayment, the server 112 also posts the payment to the broker in anelectronically accessible account.

Once the licensed copy of the digital media file has been downloaded,the processor 202 of the second device 106 stores the digital media filein memory 204, including the authorization data indicating that it is alicensed copy for the user of the second device 106. The user of thesecond device 106 may then request playback of the digital media file,and the processor 202 of the device 106 then checks the header 404 tofind the authorization data and begins playback at playback operation510.
